If your looking for an ACOG for your 308 I would say look at the TA11E. Remember to consider the cartridge the BDC was calibrated to and don't rely on the info floating around on various forums - you will get mixed results. Just call Trijicon direct and get the proper info. </div></div>

From the Trijicon website:
» 03. What bullet was used to calibrate the ACOG scopes?
The TA01, TA11, & TA31 (.223) were designed for the 5.56mm, 20 inch barrel, 55 grain bullet, and M16/AR15 carry handle mount. The TA01B & TA11C(.308) were designed for the 7.62mm, 20 inch barrel, 168 grain bullet, and M16/AR15 carry handle mount. The TA01NSN was designed specifically for the US Special Operations Command SOPMOD M4 Carbine. To meet their requirements, the reticle bullet drop compensator and range finding stadia lines were based on the trajectory of the 62 grain bullet from a 14.5 inch barrel, flattop mount (Picatinny rail Mil.Std.1913).
Trijicon FAQs
Like Sapper said, call Trijicon about the particular model you're looking at. The M240 versions are likely spec'd out for 147gr ball ammo. </div></div>
Yeah I called them and they said the ta11h was 2650fps and 175gr bullet.
